What's next... before the next academic year?

Dear S1-01

Three items are lined-up for you... in preparation for Y2016.

(A) Holiday Fun Pack

It is a collection of activities that build on the concepts and skills they learnt in Sec 1, to deepen their understanding on selected topics. It also provides opportunity for them to see Mathematics beyond the discipline, and its application in real world.

You are strongly encouraged to attempt the fun pack before school reopens.

(B) Revision Materials

A set of Revision materials is available in the GoogleSite.

The objective is to provide additional practice for those of you who needed to close their learning gaps before the next academic year. This task is optional.

If you are attempting the questions and if you come across any questions/ doubts, do send your enquiries to me during the holidays.

(C) Preparation for Academic Year 2016 (Mathematics)

In anticipation that some of you are keen to start the preparation for Y2016 S2, a set of reading assignments (using materials from the AceLearning portal) has been assigned to students.

You can also refer to the S2 textbook or access other online resources like the Khan Academy. This task is optional.

All in all, the downloadable version (PDF) of the above tasks are available in the GoogleSite (Mathematics > S1-01)

Last but not least... for those who have yet responded to the survey... do remember to complete the survey form by 30 October 2015 (Friday)

To date, the following have already responded. Thank you.

[Revision] Direct & Inverse Proportion

During the lesson, we discussed how to solve the multiple-step problem.

As mentioned, there are several ways to present the working; nevertheless, the emphasis is the clarify of working such that the marker understands your train of thought.

Below is one way you can present your working (as I used in class).
Explanation is added in red - to help you understand how the working flows.

The suggested solution for the worksheet is available in the GoogleSite:

Data Handling: Enhanced Visual Representations for Effective Communication

During this "hazy" period, the PSI values are closely tracked to inform the public of the air quality. In addition, by studying trends (together with other related elements), it enables experts to make recommendation to the public, and even decisions.

Have you visited the SGHaze Explained website?
Apart from giving facts and reporting on the situation, and to provide guidelines and advice to the public how to cope with the 'hazy' days, the website uses 2 interesting visual representations to present information to the public.

Go to the website and explore the representations shown below.

Did you notice how much more data that the enhanced representations can present compared to similar representations printed on paper?

Point to Ponder: 
1. Do you notice that the types of visuals chosen are closely linked to the context?

  • Image 1: While we can just list/ tabulate the information in a table...
    • How has this type of visual enhanced the effectiveness of information communication?
    • What are the various types of information that the visual aims to 'deliver' to the public?
    • Apart from presenting so much information, in particular, what's happening at each 'hot spot', what other possible underlying objective(s) does this visual try to communicate to the public?
  • Image 2: Similarly, information could be presented in a table (click HERE to see tabulated data on 24 & 25 Sep from NEA website). 
    • Which is a more appealing mode of presentation? Why?
    • Instead of using individual graphs for each zone in Singapore, what do you is the purpose of 'combining' the graphs into one? (omit the thought of 'saving' space)

2. We notice that each representation contains very rich information.
  • What is the purpose of providing these additional information to the public? 
  • How are these data going to be useful to the public (community at large)? What are the different groups of

Revision: Algebra

Dear S1-01

On Monday's lesson, we were revising Algebra (in class) and had revisited the following:
  • algebraic manipulation (adding & subtracting terms; multiplying & dividing terms)
  • expansion [remember: insert bracket to 'protect' the terms]
  • factorisation
    • basic rule: identify any common factor
    • look out for special products, especially (a+b)(a-b)
    • check if there's any 'square terms' (e.g. x^2) - likely to apply 'cross method'
You are strongly encouraged to view the clips on ALGEBRA in the Youtube channel as a revision.

Work for Submission
According to the revision, you should work on SST's 2014 EOY Exam Paper 2 and submit it on Monday.

As advised during lesson, before doing the paper - look through the feedback written in the marked assignments (including revision papers) so that you will not make similar error(s) when doing similar questions subsequently.

I will remain contactable via email or GChat/Hangout in the day - let me know should you need any assistance or help as you revise your work.

Number Patterns: Pascal Triangle

In Sec 1, we may associate the Pascal Triangle with the topic, Number Patterns.

Watch the clip to "see" beyond!
Something that you can relate to as you move on in the next two years... Binomial Theorem.
